To a/ZZ whom t may concern:

Be it known that I, ABRAHAM DE KUBBER, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented new and useful Improvements in Tables, of which thefollowing is a speciiication.

This invention relates to certain new and useful improvements in tables,and more particularly in the combination of an ordinary table with aremovable top which may be readily applied to and readily removed fromthe table itself.

The objects of the invention are, first, to furnish a removable top fora table, whereby the capacity of the table will be greatly increased;second, to furnish suitable means for attaching and detaching saidremovable table-top from the table; third, other objects hereinafterpointed out and claimed. These objects I accomplish by means of themechanism illustrated in the accompanying drawings, in which- Figure 1shows a side elevation of a table with my removable top applied thereto,said top extending in all directions beyond the stationary top of thetable. Fig. 2 shows a plan view of a table illustrated in Fig. 1, thecircular dotted lines showing the position of the table and of thefastener which engages with the sector-shaped sections for the purposeof retaining the same in position. Fig. 3 is a sectional view on line xof Fig. 2, showing my preferred form of attaching the removabletable-top to a non-extension table. Fig. 4 is a detail view, on anenlarged scale, of the fastening which is used for attaching thetable-top to a non-extension table. Fig. 5 is a plan view, on anenlarged scale, of the fastening when used in connection with anextension-table. Fig. 6 is a sectional view through the center of anextension-table, taken on a line corresponding with the straight dottedline of Fig. 5. Fig. 7 is a detailview of one of the sector-shapedsections of the removable table-top. Fig. 8 isa sectional view on line y'y of Fig. 7. Fig. 9 is a detail view of a modified form of fasteningused for the purpose of attaching the removable table-top to anextension-table.

Similar letters refer to similar parts throughout the several views.

A represents the removable table-top composed, in the example of myinvention shown in the drawings, of eight sectorshaped sections, (shownby D, E, F, G, H, LJ, and K,)

gaging with grooves in the apexes of the sections of the removable top,as illustrated in the drawings. This disk-shaped fastener C is providedwith a threaded shank or stud L, which engages with an internal threadon the nut M. The nut M is used in connection with a permanent table-topfor a non-extension table and is screwed into the under side of thecenter of the table-top, but not so as to project entirely through thesame. This nut M is provided with external threads N, as well asinternal threads already described, and maybe constructed in anysuitable form. The position of the nut M and its engagement with thesections of the removable table-top are fully illustrated in Fig. 3.

P is a modified form of the fastener, the

. same being modiiied to adapt it for attaching the removable top to anextension-table. The disk P is provided with a shank P and a flange Q,as shown in Fig. 6. Instead of using the iiange Q, as shown in Fig. 6,it may be made so as to constitute springs, as shown by Q Q in Fig. 9.The object of using the springs in connection with the shank P is toadapt the fastener to table-tops of diiferent thicknesses.

R andS show the two parts of an extension-table, the same being attachedtogether -by' ordinary dowel pins, as shown by T.

The dowel-pins, however, form no part of the invention. In the exampleshown in Fig. 6 the dowel-pin Tis so placed as to pass through anopening in the shank P',` although this arrangement is not necessary.

In the example of my invention shown inv the drawings I have shown thesector-shaped sections provided with a groove on one side, asillustrated by V in Fig. 7, vand a shorter tongue on the other side, asillustrated by U. It will be understood, however, that any othersuitable means may be used for securing the edges of the sectionstogether, and in case of small tables edge fastenings may be dispensedwith.

In using my invention as applied to a stationary table-top, as shown inFig. 3, the nut M is inserted from below into the permanent table-top B.The fastener C is then engaged with the nut M, and the flange portion isin position to engage with grooves in the apeXes of the sector-shapedsections of the top. These sections are shoved into place, engaging thesaid fastener C, and the apeXes of the sections meet at a common center,so that the fastener C retains firmly and securely in position all thesections of the removable top. In order to remove the top A, thesections are drawn out one by one, releasing the same from the fastenerC, when the fastener C may be removed from the table, leaving no sign ofits existence excepting a very small hole in the table-top. When myremovable table-top is applied to an extension-table, the fastener P isplaced in position centrally between the two parts R and S of the extenksionetable, and the disk P projects above the stationary part of thetable-top a sufiicient distance to engage with the grooves in the apeXesof the sector-like sections of the removable table-top. In order toremove the removable top, the sections are drawn out, so as to disengagefrom the disk-shaped fastener P. The two sections may then be slightlyopened and the fastener P removed. The size and the number of theremovable scctions will depend upon the size of the table to which thesame are applied.

I have illustrated means for detachably connecting a removable top to apermanent top; but it is apparent that my invention may be employedwithout suoli means. Vhen the permanent top is of a considerable size,the removable tcp will rest upon it, and being supported by the entiresurface of the permanent top at a considerable distance from the centerthe removable top will in many cases be supported with sufficientfirmness even if it is not centrally attached to the permanent top,while at the same time the construction shown will hold the sections ofthe removable top in perfect relation to each other and make a topsatisfactory when assembled and in use, but easily collapsible forremoval. It will be noted that the same removable top can be appliedwithout change either to an extension-table or a non-exten.- sion table,to a round table, or to a table of any other form. Ordinarily thesesections which form the removable table-top are' constructed of thinlight lumber, so as to be readily and easily handled` Having thusdescribed my invention, what I claim to have invented, and desire tosecure by Letters Patent, is-

l. In combination with the support and permanent top of a table, aremovable top therefor, composed of sector-shaped sections, and meansfor detachably securing said sec tions at their apeXes together and tothe permanent top, such means engaging with such apeXes below thesurface thereof.

2. In combination with the support and permanent top of a table, aremovable top therefor, composed of a plurality of sectorshapedsections, a slot in the apex of each section thereof, a disk engagingsuch slot in each section, and means for detachable engagement betweensuch disk and such permanent top.

3.

4. In combination with the support and permanent top of a table, arcmovable top therefor, composed of sections, a metal disk, means fordetachably engaging the metal disk with such sections below theirsurface, means for detachably engaging such metal disk with thepermanent top, and means for adjusting the metal. disk with reference tothe permanent top, whereby it will closely bind the removable top to thepermanent top.

5. In combination with the support and two parts of the permanent top ofan eXtension-table, a dowel-pin for maintaining the two parts inalinement, a metal disk for engagement with a removable top, meanscarried by such disk for vertical engagement with the permanent top, andfor lateral engagement with such dowel-pin, and a remove able topcomposed of a plurality of sections engaging with such metal disk.

6. In combination with the support and permanent top of a table,aremovable top therefor, composed of a plurality of sections, means forengaging such sections at their common meeting-point and below theirsurface with the central portion of the perma nent top, and means fordetachably engaging the side of one section to the side of the adjacentsection, such means being located between the upper and lower surfacesof the sections, whereby they are concealed from view.

7 In combination with a permanent tabletop, a removable top composed. ofa plurality of sector-shaped sections having their apeXes meeting at acommon center, such apeXes being grooved, and a disk like fasteneradapted to engage with the grooves in the apeXes of the sections and tobe entirely concealed when the removable table-top is applied, and meansfor holding such disk and such apeXes in detachable engagement.

S. In combination with the support and two parts of the permanent top ofan eXtension-table separating along a transverse line, a removable topcomposed of a plurality of IOO IIO
